American Express (Amex) chargebacks often confuse U.S. merchants due to their unique policies. In 2025, it’s more important than ever to understand how these disputes work, especially with rising fraud and stricter compliance requirements. This guide will help you navigate the Amex chargeback process, avoid preventable losses, and boost your dispute win rate.
What Makes Amex Chargebacks Different?
Unlike Visa and Mastercard, American Express operates as both the card issuer and the payment network. This closed-loop system gives Amex more control—and means fewer intermediaries but stricter policies.
Key differences:
- Amex makes final decisions on disputes
- Shorter response timeframes for merchants
- Less flexibility in appealing resolved cases
- Higher average chargeback fees
Common American Express Chargeback Reason Codes
Amex uses numeric reason codes to categorize chargebacks. Here are some of the most frequent in 2025:
F24 – No Valid Authorization
Charge occurs without proper card authorization.
F29 – Card Not Present
Dispute occurs for online or phone transactions where card was not physically presented.
C08 – Product Not Received
Buyer claims the item or service wasn’t delivered.
C02 – Credit Not Processed
Refund was promised but not issued.
C04 – Goods/Services Defective
Item was damaged or not as described.
The Amex Chargeback Timeline (2025 Update)
Understanding the timeframes is critical for a successful response:
| Event | Timeframe |
| Customer initiates dispute | Within 120 days of transaction |
| Amex notifies merchant | Usually within 7–10 days |
| Merchant response deadline | 20 days from notice |
| Final decision by Amex | Typically within 30–45 days |
⏳ Note: Inaction = auto-loss. Always respond promptly.
